The interfacial tension and adhesion at the interface mineral oil / aqueous solution of nonionic surfactants (ethoxylated izononilphenols and imides) were investigated. It was revealed that the interfacial activity of ethoxylated isononilphenols at the liquid / liquid interface is much higher than the activity of the imides was revealed. It was established that the interfacial activity is influenced by the nature of the non-polar radical, the ethoxylation degree, the temperature and the concentration of nonionic surfactant in the solution.
